Yes there are vampires, and at the moment (70% of the book) I still dont completely get why, honestly... But I'm sure I'll understand 😁

I just discovered onroutemaps, finding POIs on a provided route... Pretty nice!

Thanks weeklyosm!

OP, from China Mieville, let me suggest "the city and the city" a sort of detective story in a city that is split in 2 in a incredible and original way. I liked it more than embassytown

At the moment I'm reading Blindsight by Peter Watts, pretty mindblowing story about what life, what is conscience, what is real and what not. Still halfway

Also from the same thread:

For people who aren't intimately knowledgeable about the Seattle rail system, the Mt Baker station is an elevated platform. Meaning she had to have driven the WRONG WAY on a railroad about 40 feet up in the air for SEVERAL MILES to end up here.

Edit: it looks like it was not "several miles" but less then one mile; a notable feat anyway:

I guess that it means that train direction on that track was opposite... I don't think this makes this episode any worse πŸ€·β€β™‚οΈ

It's advertising: they think they are "free" and really wanted to have a car

I use breezy weather:

  • nice looks
  • you can add multiple locations
  • for each location and for each parameters (weather, wind, pollution) you can use a different provider
  • nice selection of widget that you can customize

My possible explanation: breaking road rules is pretty common among all categories in Italy, unluckily:

In Italy road rules are generally regarded as mild suggestions. Bikes and motorcycles on zebra crossings, cars engage in junctions even if they are not able to free them before red lights, causing gridlocks, and many things even much worse than that.

It's a general problem, but people driving cars as assholes are concretely more dangerous.

 

This is one of the most important commercial streets in Milan, and the cyclepath I'm using has been the topic of harsh discussions since the beginning, with right wing politicians wanting to take it out. The main metro line of the city runs right below this street.

It is bad because what happened with Elon could happen in the first place.

One person can control it and do what he likes with it, that's bad

 

Those who use the bike know this very well: in the city, speeding motorists overtaking other cars, only get one thing: they arrive first to the next red.

With a simple model, the author estimated the probability that one car that overtakes another, will then be reached again at a later red light. Then he estimated the probability that the same thing will happen when there are multiple successive traffic lights, as usual in the cities.

The result is that as fast as an aggressive driver goes, the presence of multiple traffic lights makes it virtually certain that a slower driver will catch up

So, if someone aggressively overcomes you, when you reach him at the next traffic light, you can tell him that it is mathematically proven that he/she is an idiot.

In addition, this study has implications for the 30 km/h city, demonstrating how in urban areas the traffic lights determine the travel times, not the maximum speed reachable between one traffic light and the next.

I understand why you write this, but collecting data is the first step when you want to change something.

Even if a femomenon sounds obvious, maybe it is not. Moreover the study analyses also why this happens, and it is pretty interesting.

 

I have always found following peertube channels from mastodon to be a rough and cumbersome experience, especially since the mastodon clients do not display videos, they need an external browser.

I found that Newpipe can show peertube videos and supports channel membership, with optional notification for new publications. It also shows likes and comments. A very smooth experience.

I guess my initial problem would be solved with peertube redirect, allowing me to open peertube videos from mastodon in Newpipe, but for now I don't feel I need this further step

 

This study from MIT used geo data collected from cars in Milan, Italy, to check the effectiveness of 30 km/h zones in reducing speed.

The first conclusion is that the signs don't work: 85 percentile speeds are all over the place in 30 km/h zones in Milan, as shown in the figure below:

85th percentile speed profiles of the 30 km/h zones in the City of Milan.

The second step was finding correlations between speeds and street features extracted from openstreetmap. Results are as expected: narrow, short, curvy sections correlate with lower speeds, as do 1 lane vs more, one way vs 2 ways:

OSM features comparison between high and low compliance Zones 30. We report the features with the lowest 𝑝-values in the Mann-Whitney U test. All 𝑝-values are below 0.001.

The final step is also interesting: the authors made a model to predict the compliance of 30 km/h speed limit on streets that are 50 km/h at the moment. Useful for urban planning to understand if charging an area to 30 km/h would need structural interventions (like bumps, narrowing of the street...) or not:

Predicted speed 85th speed percentile with city-wide adoption of limit at 30 km/h

There is so much more in the article, I suggest to read it fully.

Premise

FIAB Segrateciclabile is a local association, promoting cycling as a mean of transport, part of a national FIAB association. What follows is the translation of an Italian post where we share with members of the association why we opened an account on Mastodon (we already have Facebook an IG). I though it would be interesting to share in thos space, since I think this kind of associations should all be on the fediverse, as their values usually align much better than those of X, Facebook etc.

Why FIAB SegrateCiclabile opened an account on Mastodon

a logo where a cycle path sign bycivlrle has its frane replaced with fediverse logo

FIAB SegrateCiclabile recently opened an account on Mastodon @FIABSegrateCiclabile@mastodon.uno where we share events and news from our FIAB Ciclobby section.

What is Mastodon ?

Mastodon is a social network similar to Twitter, but with different principles. Users only see posts from those who follow, in chronological order, without ads. Unlike Twitter or Facebook, Mastodon is part of a larger network (called Fediverse) composed of many connected servers (called instances). Anyone can open one and be part of it, creating a decentralized environment. This means that no one can control everything, as it does with the big platforms.

What does Mastodon have in common with sustainable mobility?

Mastodon and the Fediverse share values with cycling and sustainable mobility, as they arise from grassroots with the aim of solving the structural problems of mainstream solutions.

Freedom and Inclusion

Unlike traditional social media, Mastodon does not require personal data to access content. It promotes an inclusive environment, where hate speech is not tolerated. FIAB is committed to a mobility accessible to all, not only to those who own a car, a driver’s license and the ability and the economic possibility of using it.

Community and Participation

Those who ride a bicycle have a deeper connection with their surroundings. The car isolates, while the bike favors genuine interactions. In the Fediverse, users can connect authentically, with no algorithms that manipulate their choices.

Democracy of the Spaces

The Fediverse represents a reaction to the commercialization of the Internet, giving control back to users. Likewise, FIAB fights to give public space back to people, not cars.

Conclusion

In an era dominated by large corporations, it is essential to enhance digital spaces like Mastodon. These instruments promote freedom of expression, inclusion and democracy, reflecting FIAB. We invite everyone to explore Mastodon and join a community that values genuine connections.

Freedom and democracy must exist in both physical and digital spaces.

EDIT: changed article link and title to comply with rules (that I didn't read πŸ˜›). The article that is linked now, links to the previous one (this one https://www.rbb24.de/politik/beitrag/2025/06/senatsverwaltung-verkehr-berlin-tempo-30.htm), and the title is the google translated of the new article, as close as original German as I can

The absurdity of the proposal is already in the title, and shows how motonormativity is spread all over the world.

Berlin has a very good public transit system, and a few 30 km/h zones cannot be that bad.

I would love to hear opinions from someone who lives there!
